I fully agree here.

Therefore we should really reconsider the no-bells-and-whistles
solution, which is also fully supported by R7RS-small, namely no
`call/kw' prefix and using symbols to introduce optional arguments (so
that they essentially appear as a plist). Apart from the syntax, this
is equivalent to CL-style. And supported everywhere.

This solves the caller-side of the problem, which is the most visible
side. For the callee-side, there can be different ways like
`lambda/kw', `define/kw' and `let-keywords'.
